The benefits of CarnoSyn® beta-alanine supplementation for muscle endurance and muscle fatigue were initially discovered by Dr. Roger Harris. Having spent years researching and patenting the benefits of creatine for muscle building, Dr. Harris turned his attention to muscle carnosine. Dr. Harris began testing other ways to increase muscle carnosine and discovered that ingested CarnoSyn® beta-alanine combined easily with naturally occurring histidine to form muscle carnosine. After testing histidine levels in the body, he determined that the limiting factor was the level of CarnoSyn® beta-alanine. It turned out that most normal diets do not include enough naturally occurring beta-alanine to increase athletic performance. 

The research staff at NAI has conducted or participated in over 55 scientific studies that have shown the benefits of CarnoSyn® beta-alanine supplementation to improve muscle endurance and support muscle strength.* Research tested effectiveness for different types of athletes, including: 

  • Professional body builders
  • High-intensity Interval Training (HIIT) athletes
  • Highly trained rowers
  • Endurance cyclists during peak power output
  • Collegiate football players
  • Competitive sprinters

“The patented use of beta-alanine has resulted in a significant advancement in muscle performance technology. CarnoSyn® and SR CarnoSyn® beta-alanine have been proven effective in over 55 scientific studies, 15 of which have been published in peer-reviewed journals." -Dr. Roger Harris.
